HENRY SCHAAKE, OF SAN FRANCISCO, CALIFORNIA.

CAN-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 548,463, dated October22, 1895.

Application filed December 18,1898. Serial No. 494,000. (No model.)

To all whom it may concern.-

Be it known that I, HENRY SCHAAKE, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inGan-Heading Machinery; and I do hereby declare the following to be afull, clear, and exact description of said invention, such as willenable others skilled in the art to which it most nearly appertains tomake, use, and practice the same.

The present invention is designed for the placing of can-heads inside ofcan-bodies and may be termed an inside heading machine for can-bodies,it belonging to that class of headers set forth in Letters Patent No.235,700, granted to George H. Pierce on the 21st day of December, 1880,and the invention relates more especially to the construction of theheader and retaining jaws, or what is more commonly known as the molds.

In the Pierce patent, No. 235,700, twooperations are required before thehead is applied to the can-body, the first being the flaring outwardlythe end of the can-body and the second forcing the end or head into theex-i panded end, the machine being an intermittent rotating one. Thisdouble operation necessarily greatly delays the heading of the can-bodyand prevents the output of a great number of cans per day.

My invention has for its object to facilitate the heading of cans byincrease in the rapidity by which the head is applied, this beingaccomplished by applying the head in one operation.

This machine is designed more especially as an improvement upon thecan-heading machine covered by Letters Patent granted to Chas. B.Kendall on the 21st day of April, 1891,No. 450,624, and like said patentI make employment of oppositely-rotating mechanisms, carrying header andretaining jaws, but with this difierence, that in my machine the head isapplied inside, while in Patent No. 450,624 the head is applied outside.By prefence I locate the oppositely-operating mechanisms one above theother, for the reason that less space is occupied by the machine, whichis an important consideration in can factories.

The manner of securing the header and retaining jaws to theoppositely-operating mechanisms, of causing the closure or bringing ofthe jaws together so as to inclose the canbod y, of feeding the canbodies and heads to the jaws, and of forcing the pistons inward so as toinsert the flange of the can-heads inside the can-body being the same inconstruction and operation as the mechanism fully set forth anddescribed in the aforesaid Letters Patent No. 450,624, detaildescription need not be given in this specification, for no claim ismade thereto except in combination with my specific improvement, whichrelates to the jaws for receiving and so holding the canbody as topermit the flange of the can-head fitting inside thereof.

In order to more fully understand my invention, reference must be had tothe accompanying sheets of drawings, wherein- Figure 1 is a verticalsectional view taken on line 00 00, Fig. 2. Fig. 2 is an end elevationshowing the trackways for forcing the header and retaining jaws to andfrom each other in order to cause the closing and opening thereof. Fig.3 is a detail longitudinal section of a headed can-body; and Fig. 4 is aside elevation of the heading-machine, showing position of the can-body,can-head, and discharge-chutes for the cans.

In the drawings, the letters A A represent two pairs of plates mountedupon shafts B B, which plates are bolted or otherwise secured to avertical frame A (See Fig. 4:.) Said plates are arranged above eachother, as shown in Fig. 1. From the inner face of these plates projectthe ribs which form circular pathways or tracks 0 G G 0 To thedrive-shafts B B, I rigidly fasten the disks D D, which are rotated andcarried around with the movement of the drive-shafts, said disks beinglocated between the stationary plates A A. These disks carry around thetrucks E E, which are mounted upon axles a a, upon the outer ends ofwhich are secured the rolls 1] h, which travel within the circulartrackways G O, and serve to throw the trucks in or out in order to forcethe header and retaining jaws G G to or from each other. These jaws aremounted upon the shafts gg. In order to facilitate and secure a perfectregistering of the header and retaining jaws I provide the rolls e e,which are held in place tion of each will be found fully set forth anddescribed in Letters Patent No. 450,624.

The present machine is provided with feedchutes for the heads andbodies, as will be seen by reference to Fig. 4, wherein J indicates thecan-body feed-chute for supplying the bodies to the jaws of the header,J the chutes for supplying the heads or ends thereto, and J the chutefor receiving the headed cans as discharged from the machine.

\Vithin the inner face of each jaw I out two semicircular grooves H 11,which when the jaws are brought together form a complete circular spaceof greater diameter than the diameter of the jaws. The materialintermediate these grooves Islightly cut away, so that the diameter ofthe jaws between the points 1 2 when closed will be greater than from 43, or that portion of the jaws which encircle the can-heads, say, forthe thickness of asheet of metal.

The can-body I when the jaws are closed will be held within the largerdiameter, the ends thereof projecting within the annular grooves andcoming flush with the inner face of the smaller diameter containing thecanheads I. .W'hen thus held, the can-heads 1' are forced into thecan-body as thepistons are moved inward by the action of the horizontalcams.

The object in providingthe annular grooves in the jaws is to permit theends of the canbody to expand somewhat as the can-heads are forcedtherein, in order that a tighter joint may be formed.

Having thus described my invention, what I claim as new, and desire tosecure protection in by Letters Patent, is-

1. In a machine for applying heads inside of can-bodies, the combinationwith a clamping device, jaw or mold which receives, clamps and holds thecan-body its entire length and which receives and holds the can-heads tobe applied inside the can-body, said holding device being made insections which when brought together entirely surround the heads andbody, the inner face of each section being cut away so as to provide aclamping device of two diameters, the larger diameter of which receivesthe can-body and holds it throughout its entire length while the smallerdiameter holds the can-heads, and of devices for automatically forcingthe heads into the ends of the can-body.

2. In a machine for applying heads to the inside of can bodies, thecombination with a device for receiving and holding the can body andheads, said device having its inner face of two diameters, the smallerdiameter of which retains and holds the can heads and the larger the canbody, the annular groove into which the ends of the can body extend, andofa device for automatically forcing the can heads into the can body.

3. In a machine for applying heads to the inside of can bodies, thecombination with oppositely operating mechanisms adapted to operatetoward each other in a vertical plane, header and retaining jaws orclamps secured to the respective mechanisms and operated therewith, saidclamps or jaws having their inner face cut away so that when broughttogether a holding device of two diameters is provided, the larger ofwhich encircles and holds the can body, the smaller diameter the canheads, and of mechanisms for automatically forcing the heads into thecan body.

4. In a machine for automatically assembling can bodies and heads andforcing the heads inside the can bodies, the combination with the canhead and can body feed chutes,

a device for receiving and holding the bodies and heads, said devicebeing of two diameters, the larger of which holds and retains the canbodies and the smaller the can heads, a device for forcing the flange ofthe heads inside the can bodies, and a discharge chute for receiving theheaded'cans.

5. In a can heading machine for assembling can bodies and can heads andforcing the flange of the heads within the ends of the can bodies, thecombination with the oppositely operating mechanisms, a section of a jawor mold secured to each mechanism which sections when brought togetherform a jaw, mold or clamp which entirely surrounds the can body andheads held therein, said jaw, mold or clamp being of two diametersinside, the larger of which retains the can body and the smaller the canheads, a device for forcing the can heads inward so as to place theflange of the can head Within the ends of the can body, and the chutesfor supplying the heads and bodies to the machine and a chute forreceiving the headed cans as discharged from the machine.

In testimony whereof I affix my signature in presence of two witnesses.
